Every transaction is confirmed by agreement of a larger part of the members in the framework. The data can never be deleted.The blocks are added to the blockchain in a linear, chronological order.

A Bitcoin

The first Bitcoin specification and proof of concept were published in 2009 by Satoshi Nakamoto, the paper was entitled “Bitcoin: A Peer-To-Peer Electronic Cash System”. Bitcoin utilizes cryptographic verification rather than the trust in the outsider (third party) for two willing gatherings to execute an online exchange over the Internet. Every exchange is secured through a computerized signature. This payment system maintains a public transaction ledger in a distributed manner. The ledger is maintained by anonymous participants (“players”) called miners, executing a protocol that maintains and extends a distributed data structure called the blockchain.
